I am still having problems with the output power in SSB mode. I have updated the firmware to the latest beta but it still is not behaving as it should. Here are my symptoms.
I set a power, any power it does not matter. I key the key to produce a tone output and see a spike at least 20% above the set power level, but only for the first transmission. After that the power drops back and stays correct until I change the power. Then the process repeats. This happens for all bands and for the transverter output. It does not happen in CW mode. You can only see it with a peak reading power meter. It is as if the ALC loop is reset each time you change power but only when using SSB. This is not a problem unless you happen to be running a linear - but then it is potentially quite damaging. I managed to get the transverter output to spike to full power ~3mW a while ago but significantly reduced the overshoot that by re-calibrating the mW power gains. I know ALC overshoot is common in some of the lesser designs like the IC706 but I had hoped the K3 would not do this. Am I alone experiencing this fault? Maybe there is an adjustment I can make to lessen it?
